William Wadsworth

William Wadsworth is Professor of Physics at the University of Bath, affiliated with the Centre for Photonics and Photonic Materials. His research focuses on photonic crystal fibres (PCFs) and hollow-core fibre technologies, with applications spanning quantum information, medical imaging, and fundamental metrology.

Research Expertise

Professor Wadsworth designs and fabricates microstructured optical fibres enabling unprecedented light control. His work centers on:

• Development of hollow-core anti-resonant fibres for deep ultraviolet guidance
• Supercontinuum generation across UV-to-infrared spectra
• Medical applications including UV light therapies and malaria diagnostics
• Quantum optical systems using alkali-metal vapours in fibres

Research Impact

His recent publications (2024-2025) demonstrate cutting-edge advances in hollow-core fibre technology for deep-UV applications and medical diagnostics. Key trends include resonance-free supercontinuum generation, integration of AI with photonics for malaria detection, and novel fibre designs enabling quantum applications. These innovations directly support UN Sustainable Development Goals in health and clean energy.

Grants and Supervision

Professor Wadsworth leads 24 research projects including:

• U-Care (2021-2026): Deep Ultraviolet Light Therapies (EPSRC)
• International Collaboration Awards (2020-2023): Clean Air (Royal Society)
